Features of the remote controller

Digital
Display

The
controller's digital display shows the actual exiting temperature of
hot water in F, or the water flow in gallons. Also, there is
an
indicator that
shows when the burner is ON and priority indicator, so when it is lit
the hot water temperature can be set. The display will flash when you
press the flow meter alarm set button. If there is a problem with the
water heater an error code (11, 90, 99...) will appear. See the list of all error codes found on Noritz tankless.

Temperature
Setting Buttons

Temperature
setting buttons are found as the up and down arrows and they are used
for setting the hot water temperature at the exit of the heat exchanger
and water heater and flow meter alarm. Keep in mind that the brand new
unit is
factory set at 110 F.

Power
Button

The power button is used to turn the water heater ON or OFF
and mute the sound (by holding it for five seconds).

Flow
Meter Alarm

Flow meter alarm set button triggers the alarm after the preselected
volume of water, in gallons, is delivered by the Noritz
tankless water heater.

How to install the remote controller

The
remote should be installed in an easily accessible location, and not
exposed to the water, steam and chemicals, or direct sunlight. It can
be installed outdoor but in the water proof box, since the unit is only
water resistant, not water proof.

Either
you are using one or two Noritz water heaters (with the use of the
Quick
Connect Multi System) only one remote controller should be
install (to one unit).

Remove the front cover of the water heater by removing the
four screws.

Run
the remote controller cord into the unit but keep enough slack so when
you remove the unit from the wall, the cord will not break.

Connect
the terminals at the end of the controller cord to the terminal block
and secure it with the clamp - Y-shaped terminal connect to water
heater; white connector to remote controller (see the picture from
above). For the extension you can buy a cord or use the 18 gauge wire
with the length up to 300 ft.

Put the front cover back.

Attach the controller to the wall by using the wall
anchors, and tie the redundant cord to outside the heater.

How to use the remote controller

Start by pressing the On/Off button. The display will show the
pre-set
temperature of 110 F so by using the up (increase) or down (decrease)
arrow you select the temperature you want. The temperature you can
select is between the minimum 98 F and maximum 140 F, while the
recommended is between 120 F and 125 F. Temperatures above 125 F can
scald so the display will flash for 10 seconds, so be aware if you have
kids around.

How to use Flow Meter Alarm

Press the Power On/Off button.

Set the water temperature on UP/Down arrow.

Press the flow meter alarm button to increase or decrease
the settings.

When
the water flow reaches the set level, the alarm will sound for ten
seconds. Stop the water manually or it will continue running (the
burner ON light is OFF). You can set the water flow from 10 gallons to
the maximum 990 gallons, with the 5 and 10 intervals. This great
feature can be used, for example, to indicate when a hot tub is full
(if hot water is not used for another application).

Resetting the Service Warning

Set the Power On/Off button to the Off.

Press the Flow meter alarm and hold for 2 seconds.

Push the button several times until it shows "7 oF".

Press the setting button (arrow up) more than 5 seconds.

Push again the Power On/Off button.

The preset temperature is shown.

Troubleshooting by using the Error Codes

As
said, you can use the remote controller to troubleshoot the problems on
Noritz tankless water heater. If the problem occurs a numerical error
code will flash,
such as the priority light and ON/OFF button.
